[LLVMdev] [llvm-gcc][patch] Use LDFLAGS from configure

[Rafael Espindola]

The attached patch permits setting the LDFLAGS variable in the call to
configure. This is the behavior of configure on gcc trunk. Not sure
why llvm-gcc is different.

This is necessary for building llvm-gcc in cases where some libraries
are in strange places:

CPPFLAGS="-I/foo/include" LDFLAGS="-L/foo/lib" configure ....

Cheers,
